This massive, megalithic tomb was home to more than 100 graves, belonging to a neolithic people that predated the iron-age Talaiotic culture on the island of Menorca. Built from enormous stones stacked without mortar, and walls packed with rubble, the tiny door leads to a passage to an upper chamber, and from there a door opens into a lower chamber. Called the Naveta for its resemblance to an overturned boat, this well-preserved tomb is one of the most famous historical sites in Menorca.
